I used Freescale OpenTCP on an MC9S12NE64. It was very disappointing.  
Could clearly see where several different people had glued one thing  
or another together. At least the NE64 version totally lacked a  
"community" which is what most people think of first when one says  
"open source". The distributed version had several stupid coding  
errors. Sending a TCP packet was not terribly easy as the stack only  
informed one of what was needed, it didn't handle retries transparently.

Had to do it over again, would pay $10k or $20k to buy a quality  
supported TCP/IP stack. Or use uIP. Or write my own. Think I spent  
more time figuring out the scrambled internals to OpenTCP than it  
would have taken to use Freescale's provided "drivers" and write my  
own stack.

The "OS" requirement for uIP can't be anything much more than for you  
to provide software timers for it to keep track of time.
